Drive shaft vibration
Post by fasteddie on Aug 10, 2006, 6:48am

Having a drive line vibration problem on a M725 . Previous owner installed 78 J20 axles , TH400 trans with 76 IH transfer case . Truck had serious vibration when driving home from initial purchase . Drive shaft was cut too short and slip yoke was worn . Had new shaft made , that took care of most of the vibration. Still have some vibration on highway around 55MPH . Was wondering if anyone ran into this problem and if a CV joint on shaft like the short CJ's would solve this . This is a daily driver and it gets a little annoying .
